The undercover BBC reporter who allegedly discovered widespread racism within a Greater Manchester Police (GMP) training school should not be prosecuted, according to a spokesman for the force's black officers.

Superintendent Martin Harding, of the GMP Black and Asian Police Association (BAPA), said they were calling for all charges against Mark Daly, who posed as a police recruit, to be dropped.

Home Secretary David Blunkett has questioned the BBC's "intent to create, not report" the story.
